That's overstated. DDI has at times reused art, but has almost always commissioned new art, including recently. Recent articles saw heavy involvement by Chris Perkins and Rob Schwalb, both as co-authors and authors. While freelancers are used, recently they have been heavy hitters. For example, freelancers that have written or co-written sourcebooks. Even if that weren't true, Dungeon and Dragon magazines have used freelancers heavily since their beginning.Things must be pretty bad at WotC HQ if they can't afford to keep the lights running on Dungeon and Dragon. It's a collection of articles mostly produced by freelancers and fans with some light editing and a little reused art.
There are two logical reasons for why the magazines are being put on hold. First, the work took away from D&D Next. Those involved with the magazines have roles to play in the next stage of D&D Next, as it moves from playtest to development and editing.
Second, sticking to 4E was contrary to business interests. I can see that. While 4E is my favorite edition, I've seen how at conventions having 4E events has confused new and casual players, or at least kept some from trying the upcoming edition. As an author for both 4E and Next, I can appreciate how it can make sense to be selective as to the kinds of Next experiences that are provided early on in the edition and how it can be challenging to make the transition, as author, from 4E to Next. It can make sense to pause and re-start with an adjusted format (or even business model) for DDI at a time when it can support sales of Next.
I'm also a big fan of Next, so I'm really okay with all of this. I have tons of 4E content. DDI articles did a tremendous job of supporting 4E, with a wide variety of content for DMs and players. While I can come up with specific articles I would like to see (Ecology of the Flumph, of course!), by and large the edition was well covered.
If I had to guess, with no knowledge whatsoever, I would guess that both Dungeon and Dragon will return. But, I would guess a new model would be used that would reduce how easy it was for gamers to subscribe a few times a year for one month and receive all the content. And I won't be shocked if they experiment with ways to get selective content for a smaller fee, or even to have content themes more closely reflect product lines. I think many fans would welcome that. (Imagine Neverwinter issues that could have supported the campaign setting, the video game, or the Encounters seasons).
